Ethereum on Web3、加密貨幣與區塊鏈技術全面解析

第 2 層（仲裁、樂觀等）的作用和 Gas 費節省

Tue, 16 Jun 2026 14:20:00 +0900

隨著以太坊用戶的增加，網路面臨高昂的汽油費和緩慢的交易。旨在解決這款擴展瓶頸的領先技術是「第 2 層」(L2)。我們研究了 Arbitrum 和 Optimism 等 L2 網絡，並檢查它們如何降低費用。

以太坊的擴容瓶頸

以太坊的基礎層（L1）優先考慮去中心化的安全性，每個區塊處理有限的交易，導致在高流量期間汽油費飆升至數十美元。

第 2 層架構

L2 網路處理從以太坊主鏈註銷的交易，將其匯總成批次，然後僅將壓縮證明發布回 L1（透過 Rollup 技術）。

費用大幅降低：捆綁交易分攤了L1結算成本，費用降低90%至99%。
即時處理：提供即時交易回饋，同時利用基礎以太坊分類帳的安全保證。

領先的 L2 生態系統

Arbitrum：L2 之間 DeFi 整合的 TVL（總價值鎖定）冠軍。
樂觀：推廣模組化 OP Stack 程式碼庫，為 Coinbase 的 Base 鍊等第 2 層設定提供支援。

什麼是 a 聰明 Contract? Learning Ethereum's Innovation

Mon, 15 Jun 2026 14:10:00 +0900

While Bitcoin operates as peer-to-peer electronic money, Ethereum’s breakthrough was introducing “聰明 Contracts.” We explain how this automated contract technology works and examine the innovations it enables.

What is a 聰明 Contract?

A 聰明 contract is a self-executing software program running on public ledgers that enforces logic rules: “If X condition is met, automatically execute Y action.”

Everyday Analogy: Vending Machines: Inserting coins and pressing a button (Condition) triggers the release of a drink (Action) without a human salesperson.

The Blockchain Edge

Running these agreements on decentralized chains generates massive efficiency gains:

Thorough 比較 of Bitcoin (BTC) and Ethereum (ETH)

Tue, 26 May 2026 13:05:00 +0900

Representing the top two crypto assets by market capitalization, Bitcoin (BTC) and Ethereum (ETH) are distinct assets. Though both are cryptocurrencies, their underlying philosophies and use cases are vastly different. We compare these two crypto pillars.

1. Bitcoin (BTC): Digital Gold

Launched in 2009, Bitcoin was engineered as a decentralized, peer-to-peer electronic 現金 system.

Objective: Store and transfer of value (Digital Gold).
Supply Cap: Strictly capped at 21 million coins, guaranteeing digital scarcity.

2. Ethereum (ETH): Decentralized Supercomputer

Ethereum is a developer platform designed to run decentralized applications and 聰明 contracts.

Ethereum's Major Upgrade 'Dencun' Outline and 效果

Sun, 19 Apr 2026 14:55:00 +0900

Ethereum’s “Dencun” hard fork upgrade is a major milestone in the network’s scaling roadmap. Introducing Proto-Danksharding, it targets Ethereum’s high gas fees. We explain the mechanics and impact of this upgrade.

The Core Feature: EIP-4844

Dencun’s central improvement is EIP-4844 (Proto-Danksharding).

The “Blob” Data Space: Previously, Layer 2 networks posted data into Ethereum’s expensive call data storage. EIP-4844 creates temporary data packages called “Blobs” that expire after a few weeks, drastically reducing mainnet data verification costs.

Layer 2 Fees Plummet 90%+

With Blobs active, transaction costs on L2 networks (like Arbitrum, Optimism, and Base) plummeted by over 90%. Users can interact with 聰明 contracts for fractions of a cent, eliminating a major user-experience barrier for dApps.
